8 Claims. 1

This invention relates to improvements in mens trousers, and more particularly to a novel is adjustable, preferably through the provision of an adjustable slidefastener, and the fly portions are constructed and arranged to preserve a neat and sightly appearance. In that construction, a slide fastener is employed to close the fly portions, and the elements of said fastener are carried by tapes which serve as a flexible connection betweenthe fly portions. Additional ma terial is provided in the body and waist portions of the trousers to permit the desired adjustment. The above-mentioned trouser construction of my earlier application supplied a long-existing need for satisfactory waist adjustability in mens trousers Without resort to unsightly devices or constructions. While the construction of my earlier application has been very successful, I have now devised an improved construction of the same general character. More particularly, I

have discovered that the trouser construction of m earlier application can be greatly improved by a certain construction and arrangement of the slide fastener elements and securing tapes on the fly portions of the trousers, as hereinafter described.

The principal object of the present invention. therefore, is to provide an improved trouser construction embodying waist adjustability, and adapted to preserve a neat and-sightly appearance of the fly portions.

The invention may be fully understood from the following detailed description with reference to the accompanying drawing wherein:

Fig. 1 is a fragmentary front view of a pair of mens trousers constructed according to a preferred embodiment of the invention, with the fly open to show the construction;

Rig. 2 is a similar view with the fly closed and with an intermediate adjustment of the Waist;

Fig. 3 is an enlarged sectional view taken along line 3-3 of Fig.2; and,

' Figsnl and are similar sectional views showing extreme conditions of adjustment.

Referring particularly to Fig. 1, the trousers i1- Iustrated comprise a flyc'ut body I, a waist pertion 2 which may be a continuation of the bodyor a waist band secured thereto, and a pair of fly portions 3 and 4. The fi'y portion 4 is adapted to overlie the fly portion 3, so that the latter is the underlying fly portion.

Preferably, though not necessarily, the side 5 of body I is cut along an oblique line 6, instead of along the usual vertical line indicated in dot and dash representation at I. By this construction, the side 5 i effectively extended circumferentially by the addition of the wedge shaped area 8 between lines 6 and I. With this preferred construction, the waist portion 2 is correspondingly extended circumferentially by the addition of the area 9 between projected lines 6 and 1. This construction allows for greater expansion of the waist portion as hereinafter described.

Adjustability of the overlappable parts l0 and l l of the waistband 2 is made possible by the provision of adjustable means, preferably a slide fastener comprising a track element ill on part It and a slider I3 on part II. Thi is a known form of slide fastener in which the slider may be locked in any position of adjustment. While the slide fastener is preferred, it could be replaced by any other adjustable means such as a series of snap fasteners or adjustable rings. Preferably, a tab M is provided on part II to cover the track element I2. Preferably also, the waistband 2 is provided with stiffening means so that the waistband simulates a belt, making it unnecessary to use the ordinary belt. Such means may take the form of ribs l5 which may be composed of a rubber-like material.

I The fly portions 3 and 4 are provided with slide fastener elements it and i1, respectively, with which there is operatively associated a slider l8. The slide fastener element I6 is carried by a tape l9 which is sewn along the seam 6 in oblique fashion so that the effective free width of the tape increases upwardly from the bottom of the fly. In practice it has been'found desirable to have the effective free width of the tape l9 about at the bottom and about at the top, although these dimensions may be varied at will. It will be noted that the slide fastener element i6 extends along the edge of tape 4 9 which is normally nearer to the free edge 20 of fly portion 3. v

The slide fastener element I1 is carried by a tape 2| which is sewn alongits edge 22 to the fly portion 4 at an angle to the free edge 23 of said fly portion. It will be noted that the tape M is further away from edge 23 at the top than at the bottom. It will benoted also that the slide fastener element l1 extends-along theedg of tape 2| which is normally further away from edge 23, which arrangement is the reverse of the arrangement of element [6 and its supporting tape and is contrary to common practice.

In addition to the stitching along edge 22, the tape 2! is stitched to the fly portion 4 along an oblique line 24 which extends downward from a point 25 about midway of the length of said fly portion to a point close to the bottom of slide fastenerelement I1. Thus it will be seen that the effective free width of tape 2| increases upwardly from the bottom of the fly to point 25. In practice it has been found desirable to have the effective free width of the tape 2! vary from a minimum dimension at the bottom of about to a maximum dimension at point 25 and above of about although these dimensions may be varied at will.

By virtue of the construction above described, the fly is caused to remain flat for any adjustment 'ofthe waist portion, and fastener elements are caused to be concealed at all times. During adjustment of the waist portion, with the.fly closed, a pivotal action of one or both fly portions takes place about the lowermost point of the fly as a pivot. By having the effective free width of the tapes I9 and 2| increase upwardly, the pivotal action is permitted and all unnecessary tape material is effectively eliminated, so that no bulging is produced by excess material at any point. By virtue of the arrangement of tape 2! and the provision of stitch line 24, the fly portion 4 is caused to cover the slide fastener elements at all times when the fly is closed. Also, by having the fastener element I1 and its tape 2| arranged as above mentioned, the relative movements of the fly portions are facilitated and said portions are better maintained flat. and furthermore a large range of adjustment is made possible.

Figs. 3 to 5 serve to show the action which takes place during adjustment and also serve to show the positions of the elements for different conditions of adjustment. Fig. 3 shows the condition of adjustment approximately midway between the two extreme conditions of adjustment. In-this instance, the tape 2| is folded adjacent the fastener element l1. Fig. 4 shows the extreme condition of adjustment for the largest expanse of the waist portion. In this instance, the tape 21 is folded sharply adjacent the edge 22. Fig.5 shows the other extreme condition of adjustment for maximum contraction of the waist portion. In this instance, the tape 2| is in its normal unfolded condition while tape I9 is folded and the slide fastener is turned over in relation to fly portion 3 and in contrast to its position in Figs. 3 and 4. It will be noted that in all conditions of adjustment, the fly is maintained flat and the slide fastener is well concealed.

It will be seen from the foregoing'description that an important feature of the trouser construction resides in the fact that the securing tapes for the fly closure elements increase in effective free width upwardly from the bottom of the fly portions. In the specific illustration, this result is achieved by using ordinary rectangular-tapes and stitching them in a certain manner. However, the same result could be achieved in other ways, for example, by using specially-cut tapered tapes stitched along their .edges.

has proved to be a very desirable improvement of the construction disclosed in my aforementioned application. The present construction constitutes a complete and practical solution of the problem of providing adjustable-waist trousers without resort to unsightly devices.

It will be understood, of course, that the invention is not limited to the specific structure shown and described, which represents only one embodiment of the invention. Various modifications and other embodiments will be apparent to those skilled in the art and are considered to be within the scope of the invention.
